THlLL-COUPLlNG.

SPECIFICATION forming part of Letters Patent No. 783,487, dated February28, 1905. Application filed January 25, 1904. Serial No. 1?]0505.

1'0 (tZZ whom. it may concern.-

Be it known that I, EDWARD XVALTER, a citizen of the United States.residing at Keytesville, in the county of Oharlton and State ofMissouri, have invented new and useful lmprovemcnts in Thill-Oouplings,of which the following is a specification.

My invention relates to improvements in thillcouplings, and has for itsobject a construction whereby the thills may be coupled to the axle of avehicle without the use of bolts, screws, or rivets and also to providemeans for preventingrattling. 1

A further object is to provide a coupling which shall be simple inconstruction, having no complicated parts to get out of order, and whichshall withal be thoroughly reliable in operation.

in the accompanying drawings, Figure 1 is a side elevation of theinvention. Fig. 2 is a front elevation. Fig. 3 is a vertical sectionalView. Fig. 4 1s a plan view wlth the thilliron removed. Fig. 5 is a planview of the thill-iron.

Referring to the drawings, 7 indicates a metal block having a socket 8to receive the thilliron 9. Arms 10 extend rearwardly from the blockacross the top and bottom of the axle 11. A, bolt 12extends through theends of the arms, by which they are drawn together against the axle,whereby the coupling is securely held in place thereon. Shoulders 10abut against the rear of the axle and strengthen the hold of the armsthereon.

The thill-iron has a cylindrical head 9, which tits in the socket 8. Theshank of the thilliron extends through a slot 13 from the socket to theoutside in front. This slot also forms shoulders 13 in the socket,against which the head of the thill-iron bears and which prevents itswithdrawal.

The socket opens toward the top of the block and contains a block 14 ofrubber or other elastic material, against which the head of thethill-iron bears and whichretains it in the socket and also preventsrattling. The block 14 is held in place by a strap 15, which extendsaround the block 7 and is fastened thereto by a wedge-key 16, whichextends through slots in the free ends of the strap, the bottom of theblock 7 having a groove 7 to receive the key. The key has a suitable endlock, preferably a transverse pin 17, extending through a hole in theend thereof.

The coupling is readily attached by spreading the arms 10 apart andslipping them over the axle, after which the bolt 12 is inserted andtightened up. The arms are formed of suitable spring metal. Thethill-iron is placed in the socket, the block 14 first being removed.The block is then placed in the socket and secured. by a strap 15, thelatter being fastened as heretofore described. The device is readilyattached and removed, and when the block 1% is worn it can beconveniently removed and replaced.

Having thus described my invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

A thill-coupling comprising a block having a socket to receive thethill-iron and arms which extend rearwardly across the top and bottom ofthe axle and have shoulders extending behind the same, a bolt throughthe arms behind the axle, an elastic bearing-block in the socket on thethill-iron, a strap around the socket-block over the bearing-block, anda wedge-key extending through the free ends of the strap.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
